WYSIWYG Systems

I WYSIWYG = “What You See Is What You Get”.

I What you type in can be seen directly on the screen.

I Microsoft Office Word is the main example of a WYSIWYGsystem.


Advantages/Disadvantages of WYSIWYG Systems

I WYSIWYG systems are relatively easy to use.I In WYSIWYG systems typesetting to be done by the user.

I Problem: most users are not professional type setters.

I In most systems (e.g. Word) you can see only the output, butnot the formatting information.

I Difficult to detect that one headline is in 11 pt and another in12 pt, or one headline in one font, and another in a slightlydifferent font.

I Therefore output is usually inconsistent.

I Usually output not of printable quality.

I Programming is difficult, no possibility for defining macros (ordefinition of macros restricted).


WYSIWYM

I WYSIWYM = “What You See Is What You Mean”.I Instead of doing the typesetting directly the user says:

I This is a headline.I This is a section title.I This text is normal text.I This is a mathematical formula

I Main examples: TEXand LATEX.


Advantages/Disadvantages of WYSIWYM Systems

I Steeper learning curve.

I Separation of output from input, therefore what you writeneeds to be compiled into text.

I Can create text in print quality.I Many publishers print articles typeset in LATEX directly, or after

adding their own generic macros.

I User sees all formatting information and can therefore producevery uniform text.

I Programmable using macros.I Development of macro packages for many purposes.

I In LATEX macro packages e.g. for chess, for typesetting proofs,chemical formulas exist.

I These slides are typeset in LATEX.


LATEX

I TEX developed by Donald Knuth in order to typeset a newversion of his books “The art of Computer Programming”.

I LATEX (for Lamport-TEX) developed by Laslie Lamport inorder to make a more userfriendly version of TEX.

I LATEX is essentially a macro package on top of TEX.


Use of LATEX for Reports and Dissertation

I Reports and dissertations can be written using any textprocessing system.

I Use of LATEX will in many cases give you a slight advantagebecause of the higher quality of the output.

I Many lecturers (but not all) use LATEX, especially for scientificpublishing.

I They might help you with LATEX.


Example

I The following shows an example of LATEX code (split into 3codes) plus the output.

I For ease of presentation after each code piece the final output(which is only produced after running latex on the wholecode) is shown.

LATEXOutput


Example (Continued)

\LaTeX{} is a document preparation system for the \TeX{}typesetting program. It offers programmable desktop

publishing features and extensive facilities for

automating most aspects of typesetting and desktop

publishing, including numbering and cross-referencing,

tables and figures, page layout, bibliographies, and

much more.

\LaTeX{} was originally written in 1984 by Leslie

Lamport and has become the dominant method for using

\TeX; few people write in plain \TeX{} anymore.

The current version is \LaTeXe.\LaTeX{} plays an important \role{} in publishing

scientific articles in Science.

Example (Continued)

% The following shows a little of the typesetting power

% of LaTeX:

\begin{align}E &= mc^2 \\m &= \frac{m 0}{\sqrt{1-\frac{v^2}{c^2}}}\end{align}\end{document}

More Details

I \documentclass[12pt]{article}I Standard Header of a Latex file.I 12pt = font sizeI article = style

(Article is suitable for reports.There are lots of other styles.Style “book” is the simplest style for dissertations.– There are many more fancy ones.)

I \usepackage{amsmath}I Loads package amstmath.I Rich package for mathematics, here used for command \frac.I Lots of packages are available.

I \title{\LaTeX}I Defines the title.I \LaTeX{} is a macro typesetting LATEX.

I \author{Anton Setzer

I Starts defining the author (note { not closed yet)


More Details

I \thanks{Dept. of Computer Science,

Email: {\tt [email protected]}.This article is based on the example in

Wikipedia,http://en.wikipedia.org/wiki/LaTeX}}

I Footnote added to author.I {\tt · · · } type sets this part in type writer font.I Second “}” finishes definition of author.

\date{7 October 2011}I Defines the date.


More Details

I \newcommand{\role}{{r\^{o}le}}I Defines a macro.I From now on \role will expand to{r\ˆ{o}le}.

I Curly brackets will be used to group text but will not beprinted.

I \ˆ{o} typesets oI There are macros for defining lots and lots of special symbols.I http://www.tug.org/tex-archive/info/symbols/comprehensive/I Macros can have parameters as well.


More Details

I \begin{document}I Start of the content of the document.

I \maketitleI Puts title, author, date at this position.I Without this command no title, author, date will occur in the

document.


More Details

I \LaTeX{} is a document preparation system for the\TeX{} typesetting program. It offers · · ·

I This is standard text to be typeset.I Aligning the text done by the system.I Line breaks in the text create only space between words.I Double line breaks creates a paragraph

(Equivalently one can use the macro \par).I Several blanks, tabs, line breaks are the same as a single space

(except for double line breaks).I \TeX{} typesets TEX.


More Details

I \LaTeX{} plays an important \role{} in publishing

I Here the user defined macro \role{} typeset as role is used.I {} here makes sure that there is a blank after LATEXand after

role.Spaces after a macro are ignored.

I % This is a comment; it will not be shownI Everything in a a line after % is a comment


Example (Continued)

I \begin{align}· · ·\end{align}

I Example of an environment.I There are many environments in LATEX.


Example (Continued)

I \begin{align}· · ·& · · · \\· · ·& · · · \\\end{align}

I Environment align typesets several formulae, which arenumbered as (1), (2) consecutively.

I Content of an align environment is mathematical text.I LATEX and TEX have a text mode and a formula mode.I In formula mode different macros (usually for creating

mathematical text) are used.I In mathematical text all blanks are ignored.I Mathematical text is where the full power of LATEX/TEXis

shown.I Seems to be the easiest system for typesetting formulae.

I \\ separates lines in mathmemtical text (can be used forordinary text as well).

I Symbols & mark positions to be aligned.


Example (Continued)

I cˆ2I Typesets c2 in mathematical text.

I m 0.I Typesets m0 in mathematical text.

I \frac{· · · }{· · · }I Type sets a fraction ···

··· .I Note that we can nest fractions.

I \sqrt{· · · }I Typesets

√· · ·.

I \end{align}I End of align environment.

I \end{document}I End of the document.I Text after this will be ignored.


LATEX under Windows

I Use any texteditor. Recommended: Emacs or XEmacs.

I MikTeX is a LATEX compiler for Windows.

I For viewing dvi files use the included YAP dvi-viewer.

I For postscript use GhostScript + GSView.

I See for instancehttp://www.pinteric.com/miktex.htmlon how to use LATEX under Windows.

More to Come

I Lots of documentation on LATEX (tutorials, userguides etc)available online.
